Too many smileys make no point in particular. However, one or two in the right place help convey the right intent that sometimes cannot be expressed in words alone. 'I don't think your idea can exist' said with a poker face is not the same thing when said with a smile?

What Kris said. But I'm not going to edit the smileys back in. @Jcubed, please note that my tone is intended to be light, not condemning. I think you've raised an interesting question or I wouldn't have bothered with an answer.
